My local Ram Dealership in Del Rio, Texas (Ram Country), has refused to repair my open recalls on my 2021 Ram 2500 Diesel. This includes the heater relay recall and the transmission dipstick recall. I have visited the dealership on at least 5 occassions and each time I am put on a new "waiting list". Ram Country has informed me that they get parts weekly and will call me to schedule needed repairs, however they never do. What can I do to get my recalls fixed, and finally closed. I get FCA recall notifications warning me to get my recalls completed, however again, my local Ram Dealer refuses to schedule a repair, and continues putting my on a waiting list, and has recommended that maybe I should get a new vehicle. For your information........I paid $75,000.00 for my truck 22 months ago, and I cant buy a new truck everytime the manufacturer refuses to make a diligent effort for recall remediation. I need help please..........

This problem first occurred on a state highway in [XXX] in 2023 and again in 2026 (this incident.) While driving south on XXX, there was an undulation/slight bump in the interstate while in a mild right hand curve. My vehicles brakes engaged without my input and slowed me down from 70mph to 35mph with traffic behind me. My gas accelerator and brake pedal were unresponsive from user input. At no point was my vehicle out of control to trigger such aggressive braking from my ESC, ERM, or ABS. The concern here is that thankfully this was on dry roads and traffic was far enough behind me to avoid a collision. My concern is this happening in winter weather/icy/wet roads, or with significant traffic behind me causing a possible high speed rear-end vehicle accident. There was a safety recall for ESC/ABS a few years ago on my vehicle that I dealt with through the dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Ram 2500. The contact stated that upon driving several miles and refueling the vehicle, he noticed that the Diesel Exhaust Fluid (DEF) additive gauge remained stuck in the same position. There was no warning light illuminated. The dealer was notified of the failure and informed the contact that it was a known failure and that the failure would persist even after the repair. Upon investigating the failure, the contact discovered that the failure mainly occurred in cold weather due to the DEF additive crystallization in cold temperatures, causing the additive gauge to be stuck in the same position. A message indicating to add a DEF additive in the vehicle for safety was displayed. The vehicle was not repaired. Additionally, the contact stated that the tailgate latch had fractured due to cold weather and had been replaced three times by the dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 8,000.

I have been on a waiting list for more than 6 months at Christopher’s dodge world in golden Colorado for completion of mandatory safety recalls on my vehicle. The parts are available and these critical safety recalls have not been performed. I receive automated messages from FCA informing me that these recalls are required yet never have received a call from the dealer to actually schedule them. I have been told the parts are unavailable when I call and that I am deep down a waiting list and “I will be contacted when my number comes up”. I have contacted “ram cares” via automotive forums and they are no help either. The recalls keep piling up on vehicle vin [XXX] They are a fire risk and safety risk and FCA acknowledges this yet over a year and a half later my vehicle has never been able to be seen for completion of these required recalls. The recalls currently incomplete are: Z20 ZA3 ZB8 13A INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a seized brake caliper that is a direct result of a faulty brake hose. The brakes were looked at by a brake specialist business and I was told the brake hoses had to be replaced as well as the calipers, rotors and pads on the front. I took it to the Lake City, Florida dealer looking for a recall after reading online that some 2021 Ram 2500 trucks had brake hose recalls. They told me there was no recall on my particular truck for brake issues. However, when they quoted me there price and reason they needed to repair is that it had a seized brake caliper and all components are now no good. They also told me the brake hoses need to be replaced due to the passenger side brake hose having collapsed internally but they want me to pay $3500 to repair. This issue is a direct result of a faulty brake hose that they said collapsed. There are other trucks that have recalls for the same failure. Why is mine not covered under a recall with the safety issue that has developed? I need these parts covered as well as all the parts that have to be replaced due to the faulty hose. Please let me know what to do.

I recently bought this truck used from a Ford dealership. The next day when I was taking my wife for a short drive. I noticed the engine light was on the dash display. I the same time the truck started accelerating Like it was on cruise control and returning to a higher speed. The cruse control was not set when I tried to access the cruse control I would get the message that it was unavailable at this time. I had to stop the truck and turn the truck off. When I restarted the engine light was still on, but the acceleration stopped. I drove to the dealership to see if they had any information or recalls but by the time, I got there the engine light was off and their computer did not tell them anything. This has now happened two times. The dealership says I must bring the Truck in while this is happening. for them to get a reading. This is not my primary vehicle, and I don't drive it all the time and it is 45 minutes from any dealership. The uncontrolled acieration is a safety issue. The problem has not been reproduced Dealer thay had no idea what was happening. The warning lamp engine and the cruse control not available message., I am wondering if anyone else has had the problem?

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11428902

I was driving my 2021 ram 2500 west at approximately 35mph when a oncoming vehicle a 2008 Dodge Nitro failed to navigate a curve in the road crossing center line of road hitting me head on at a estimated 50-6- mph. (Driver was ticket for to fast for conditions) It was a clear , dry day. The Ram trucks air bag and seatbelt restraint system did not deploy/lockup . There were no warning lights , messages, or symptoms making me aware of any problems. The vehicle was towed from the scene, incapable of moving on its own. Vehicle has only 2000mi. The vehicle was inspected by insurance company and found to need a complete new frame due to the impact. 100s of people from police officers to dealers to service managers for Ram cannot believe that there was no airbag deployment or seatbelt restraint. Ram had a independent person inspect vehicle and and within 48 hours Ram sent me a email saying THE RATE OF DECELERATION NESSARY TO ACTIVATE THE AIRBAG SYSTEM WAS NOT THERE IN THUS ACCIDENT. I really disagree with Ram in this case as does Everyone That has seen the vehicle. When a 8000lb truck gets hit hard enough from a 3000lb car to knock it off the center of road and up over the curb that should have been more than enough impact to make my safety devices in my vehicle work as expected. If this accident did not provide enough acceleration for my safety equipment to work I believe along with many others that something in design is flawed.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11703074

I am reporting a serious safety issue with my 2021 Ram 2500 (VIN: [XXX] ). The truck has experienced three separate transmission failures within a few months. Each time the transmission was replaced, the vehicle failed again shortly afterward. At one point, the dealership returned the truck to me without transmission fluid, causing additional internal damage and creating an extreme safety risk. I have also had steering issues since the truck was new, which continue today despite multiple service attempts. Shortly after purchase, the truck developed severe mold and water intrusion after the roof stop lamp was removed or stolen while the vehicle was at the dealership for service. This caused water to leak into the interior and contaminate the carpet. The dealership replaced the carpet but the issues continued. The repeated transmission failures, steering defects, and water intrusion have made this truck unsafe to drive. The vehicle has lost significant value, and the dealership and manufacturer have been unable to correct the defects after numerous attempts. I am requesting an NHTSA investigation into these issues, including: •Repeated transmission failures •Ongoing steering defects •Improper repair practices •Water intrusion and mold exposure •Dealer negligence These failures represent a serious safety hazard to both myself and others on the road.

Government / agencyIndexed Oct 9, 2026Source-linkedVerify source — NHTSA complaint #11541283

On February 9 2023 Ram issued a recall on my vehicle Ram 2500. In that recall it was noted “ An electrical short in the relay can potentially lead to a vehicle fire with the ignition on or off” further owners were advised to park their vehicles outside and away from buildings. This requirement is a burden on vehicle owners and subjects the vehicle to additional risks including weather (hail, extreme heat, and paint oxidization) and other risks such as vandalism and theft. You would think stellantis would have a sense of urgency to complete these recalls, they obviously do not. I have contacted the dealer Waxahachie Ram multiple times to only receive the same answer… we don’t have the part, we only get one every two weeks, we’ll call ya. Reading consumer complaints on NHTSA, multiple consumers have had the same experience. A manufacturer issuing a recall is meaningless if they don’t repair the vehicles. Stellantis has demonstrated they have total disregard for the consumers who owns these affected vehicles by exceeding a reasonable amount of time to perform these repairs and keeping consumers in unsafe vehicles. Unlike your other complaints, I ask NHTSA to not just contact the manufacture and fall for their “parts distribution disconnect” response. This is clearly a failure on Stellantis to repair a recall on a reportedly 306k vehicles recall. I ask the NHTSA not to just call Stellantis but to investigate the actions and inactions they have taken to timely complete these repairs. Investigate if there is a financial benefit to Stellantis to delay these repairs. Investigate if the replacement part is identical to the ones used on newly manufactured rams and if so investigate why those units would have an available part or get priority at the dealership (vehicle sale?)vs essentially no parts available for the already sold units. Is Stellantis allocating these parts to timely repair the affected vehicles? A real investigation needs to find out!

The 68RFE automatic transmission in this 2021 Ram 2500 6.7L Cummins fails to engage reverse when the transmission reaches operating temperature. When the gear selector is placed in reverse and the accelerator is applied, the engine revs but the truck does not move. The defect is intermittent and temperature-dependent, which means it cannot be predicted or avoided by the driver. The vehicle is used to tow an enclosed cargo trailer weighing approximately 7,000 pounds.The safety risk: inability to engage reverse on demand creates a hazard in any situation requiring reverse motion, including backing away from a stopped vehicle, reversing out of a fuel station, backing a loaded trailer at a campground or boat ramp, or executing an evasive reverse maneuver. With a trailer attached, loss of reverse function can leave the truck and trailer stranded in active traffic lanes or at intersections.The defect was first reported to a dealer in August 2023 with diagnostic trouble code P2701 stored (Friction Element B implausible pressure, internal transmission fault). The code was logged but not addressed at that visit. Over the following 32 months the same defect was reported to the same dealer four additional times. On the fourth visit the dealer replaced the complete transmission and torque converter under warranty and certified the repair complete after a documented 77 mile dealer test drive. The same defect returned approximately 4 customer miles after the truck was returned to me. The truck is currently at the dealer for the fifth repair attempt, with the dealer's own write-up confirming that the vehicle will not move while in reverse at operating temperature.The defect has been confirmed by the dealer service department through their own diagnostic process, has been documented across five repair orders, and has resulted in a complete factory transmission and torque converter replacement that failed to resolve the issue.Warning indicators: a P2701 diagnostic trouble code was s

I am writing to formally follow up regarding complaint/case number 97989810 through Dodge and to request that this matter be elevated for a complete technical review concerning my 2021 Ram 2500 6.7L Cummins, VIN [XXX]. Time - Line PRIOR FACTORY-WARRANTY REPAIR The XXX factory-warranty repair is an important part of this vehicle's mechanical history. That repair involved the timing-cover/timing-gear-case area and front crankshaft seal. As part of that repair, the harmonic balancer/vibration damper was removed and reinstalled. Approximately 26,000 miles later, the vehicle experienced a failure involving the vibration damper and its associated mounting bolts. +++ Vehicle receipt will be attached XXX took vehicle Naples Dodge after large thump and vehicle would not move Per dealership - Finding - Advise it was an after market tune that caused harmonic balancer got loose and sheered the bolts Ongoing the dealership provided video and several reports that it was an after market tune no coralation between the 2024 service and findings today Findings: Cummins Service Technician XXX technician report In XXX Cummins filed a safety recall with the NHTSA (Campaign ID 24V-192) concerning certain engines equipped with vibration dampers are the critical details of the recall:The Issue: The front vibration damper capscrews (mounting bolts) were not torqued to specification during assembly. If left unaddressed, the capscrews could fracture or loosen, potentially causing the vibration damper to separate from the engine. This creates a high risk of personal injury, mechanical failure, or property damage.(Note: If you are looking for Dodge Ram trucks, Cummins also issued a Technical Service Bulletin—TSB210097—addressing fluid degradation and capscrew fractures on viscous vibration dampers for B6.7 engines, though it was handled as a service bulletin rather than a sweeping automotive safety recall).
